Accés obertWe propose a method to characterize electrical resistor damage based on entropy measurements. Irreversible entropy and the rate at which it is generated are more convenient parameters than resistance for describing damage ...

Accés restringit per política de l'editorialThe use of Optical Backscatter Reflectometer (OBR) as a distributed fiber optic system to measure strain and detect cracking in concrete structures is investigated. A laboratory experience in a concrete slab is first ...
Accés restringit per política de l'editorialThe HG-A in situ test, located at the Mont Terri Underground Rock Laboratory (URL), was analysed as part of the FORGE project. This test investigated the behaviour of the excavation damage zone (EDZ) around a backfilled ...
Numerical homogenization for composite materials analysis: comparison with other micro mechanical formulations (2015-04)
Accés restringit per política de l'editorialThis work presents a two-scale homogenization procedure to analyze three dimension composite structures by FEM. The theory implemented is compared with other micro-structural formulations: micro models and serial parallel ...
(Universitat Politècnica de Catalunya, 2013-05-13)
Accés obertTo numerically simulate a failure process, damage models can be used. In order to avoid mesh dependency problems of local damage models, nonlocal models are employed. The use of nonlocal displacements is an efficient ...
Reduced kinematic formulation based on the strong discontinuity method for reinforced concrete components (CIMNE, 2015)
Text en actes de congrés
Accés obertDamage models, developed in the last decades, insure a continuous description of the fracture process zone in quasi-brittle materials but fail at representing fine information of the cracking features such as openings and ...
(Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2014)
Accés restringit per política de l'editorialThis work investigates systematically strain localization and failure mechanics for elastoplastic damage solids. Two complementary methodologies, i.e., traction-based discontinuities localized in an elastic solid and strain ...
Accés restringit per política de l'editorialCable-stayed bridges are highly statically redundant, light and flexible structures. This complexity highlights the role of the structural system identification (SSI) method in the calibration of the actual properties of ...
